A navigation system is disclosed. The navigation system includes an image capturing device, a positioning device, and a processing device. The image capturing device is configured to capture an image of an object fed by a user. The positioning device is configured to obtain positioning information of the navigation system. The processing device is configured to: calculate a feature code based on features of a logo in the image; retrieve a piece of address information of a location corresponding to the feature code from a database; and calculate a route from the current location to the location corresponding to the piece of address using the positioning information and the piece of address information. A navigation method is also provided.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A navigation system, comprising: an image capturing device, configured to capture an image of an object fed by a user; a positioning device, configured to obtain positioning information of the navigation system; and a processing device, configured to calculate a feature code based on features of a logo in the captured image; retrieve a piece of address information of a target location corresponding to the feature code from a database; and calculate a route from a current location to the target location using the positioning information and the piece of address information, wherein the processing device is further configured to: determine whether a barcode is contained in the image; retrieve the piece of address information of the target location corresponding to the barcode from the database in response to determining that the barcode is contained in the image; and calculate the feature code based on the features of the logo in response to determining that the barcode is not contained in the image.
2. The navigation system according to claim 1 , wherein the piece of address information of the target location is a text address.
3. The navigation system according to claim 1 , wherein the piece of address information of the target location is a latitude and a longitude of the target location.
4. The navigation system according to claim 1 , wherein the processing device calculates the feature code using a scale invariant feature transform algorithm.
5. The navigation system according to claim 1 , wherein the positioning device is a Global Positioning System (GPS) device, and the positioning information is a longitude and a latitude of the navigation system.
6. A navigation method, comprising: capturing an image of an object fed by a user; calculating a feature code based on features of a logo in the captured image; retrieving from a database a piece of address information of a target location corresponding to the feature code; obtaining positioning information of a current location; calculating a route from the current location to the target location using the positioning information and the piece of address information; determining whether a barcode is contained in the image; retrieving from the database the piece of address information of the target location corresponding to the barcode in response to determining that the barcode is contained in the image; and calculating the feature code based on the features of the logo in the captured image in response to determining that the barcode is not contained in the image.
7. The navigation method according to claim 6 , wherein the piece of address information of the target location is text address.
8. The navigation method according to claim 6 , wherein the piece of address information of the target location is a latitude and a longitude of the target location.
9. The navigation method according to claim 6 , wherein the positioning information is a longitude and a latitude of the current location.
10. The navigation system of claim 1 wherein the logo is indicative of one of a product and service.
11. The navigation method of claim 6 wherein the logo is indicative of one of a product and service.
12. A navigation system comprising: an image capturing device configured to capture an image of an object; a positioning device configured to obtain positioning information of the navigation system; and a processing device configured to: calculate a feature code based on features of a logo indicating one of a product and service in the captured image; retrieve a piece of address information of a target location corresponding to the feature code from a database; and calculate a route from a current location to the target location using the positioning information and the piece of address information, wherein the processing device is further configured to: determine whether a barcode is contained in the image; retrieve the piece of address information of the target location corresponding to the barcode from the database in response to determining that the barcode is contained in the image; and calculate the feature code based on the features of the logo in response to determining that the barcode is not contained in the image.
13. The navigation system of claim 12 , wherein the piece of address information of the target location is a text address.
14. The navigation system of claim 12 , wherein the piece of address information of the target location is a latitude and a longitude of the target location.
15. The navigation system of claim 12 , wherein the processing device is further configured to calculate the feature code using a scale invariant feature transform algorithm.
16. The navigation system of claim 12 , wherein the positioning device is a Global Positioning System (GPS) device, and the positioning information is a longitude and a latitude of the navigation system.
17. The navigation system of claim 12 , wherein the image capturing device is further configured to capture the image of the object as provided by a user.
